MK 12 mod h help

[7n6]

Hello building out a mk12 mod h clone and am going to be running it suppressed with an aem5 can. Does anyone know the preferred or correct gas port size necessary if running this gun with that suppressor?

You should be able to purchase a the correct Douglas Mod H barrel from PRI; it will have the correct gas port size and run perfect with the AEM5…

I really never hear of MK12s being overgassed.

take a look here for the Mk12 ModH barrels and AEM hardware to fit and AEM5.

Should be .750". Centurion makes them to Crane spec here: ( https://centurionarms.com/mk12-barrel/ )

Edit: depending how clone correct you want to get the mod H had FDE ceracoated Noveske barrels.
